Terminal Block Connector
The back of the EDS4100 has a socket for a terminal block screw connector (not included) for
attaching to an appropriate power source, such as those used in automation and manufacturing
industries. The terminal block connector supports a power range from 42 VDC to 56 VDC. It can
be used with the EDS4100's barrel power connector and PoE capabilities as a redundant power
source to the unit. Vendors who do supply this connector can be found by doing a web search for
part 'Phoenix 1803581 MC 1,5/ 3-ST-3,81'.
